This document discusses a proposed dynamic trust management protocol for delay tolerant networks (DTNs) to deal with both malicious and selfish nodes. The protocol aims to optimize routing performance in DTNs in response to changing network conditions and types of misbehaving nodes. Simulation results show that the trust-based routing protocol can improve delivery ratio compared to other protocols while balancing message overhead and delay. It also demonstrates resilience against trust-related attacks from malicious nodes.

Behavioral malware detection in delay tolerant networks
The document discusses behavioral malware detection in delay tolerant networks. It proposes using a Naive Bayesian model to characterize proximity malware based on behavior. It identifies two challenges for applying Bayesian detection in DTNs: insufficient evidence collection risk and filtering false evidence sequentially and distributedly. It proposes a method called "look-ahead" to address these challenges, as well as two extensions - dogmatic filtering and adaptive look-ahead - to address malicious nodes sharing false evidence. Real mobile network traces are used to evaluate the effectiveness of the proposed methods.
Behavioral malware detection in delay tolerant network
This document proposes a system for detecting behavioral malware in delay tolerant networks. It presents a general behavioral characterization of proximity malware based on a naive Bayesian model. This model has been successfully used to detect malware in non-DTN settings. The system addresses challenges in extending this model to DTNs, including having insufficient evidence due to limited node contact and the risk of collecting evidence from infected nodes. It proposes techniques like look-ahead and adaptive look-ahead to balance these risks.
Y-HAMILTONIAN LAYERS BROADCAST ALGORITHM
The document proposes a new broadcasting algorithm called Y-Hamiltonian Layers Broadcast (Y-HLB) for wormhole-routed 3D mesh networks. It divides the 3D mesh into layers that are modeled as Hamiltonian paths. The Y-HLB algorithm routes messages along these Hamiltonian paths in an efficient manner to broadcast to all nodes. Previous related work on broadcasting algorithms for wormhole-routed 3D meshes are also discussed, including how they divide the network and route messages. Simulation results show Y-HLB performs better than these previous algorithms in terms of reducing broadcast latency.
The apt identification and blocking through ids in manet
This document summarizes research on detecting and blocking advanced persistent threats (APTs) in mobile ad hoc networks (MANETs) through an intrusion detection system (IDS). The research proposes applying an IDS to identify and prevent APT attacks from malware like viruses, worms, and trojan horses that could spread in the dynamic MANET topology and degrade network performance. The IDS would monitor nodes, identify suspicious activity based on differences from normal behavior patterns, and block identified attackers to secure the MANET from unauthorized access and data theft or modification by APTs.

A mobile Ad-hoc network (MANET) is an impulsive network that can be recognized with no predetermined infrastructure. To achieve safe path selection cryptographic key exchange was implemented mostly in turn of huge computational cost. Confidence based coordination in MANET focuses on routing challenges created by selfish nodes, as energy utilization & time factor are key issues in this aspect. The present protocol is focused on fuzzy optimization-based node confidence estimation and path selection with minimum energy utilization. The node with maximum confidence value will give high priority to include in the path for transmission. In the implemented protocol to build a novel confidence-based model multidimensional factors like confidence value, link cost, degree of node and node energy are included as decision-making factors. The proposed protocol CLBNSRM estimates confidence level in four steps to decide a trustworthiness of neighboring node. To estimate the efficiency of the present confidence model various protocols are compared by using attributes like the number of nodes, node speed, malicious node variation, etc. Moreover, different parameters like Packet delivery ratio, Throughput, Residual energy, and Packet dropped are considered with these attribute variations. Experimental results indicate that PDR and Throughput increase although in presence of malicious nodes, along with the utilization of minimal energy. Statistical analysis is carried out for mathematical modeling. This analysis shows that a linear model of an implemented protocol is better than compared protocol with all the aspects.
Introduction to Secure Delay/Disruption Tolerant Networks (DTN)
This document introduces delay/disruption tolerant networks (DTNs) and their security architecture. It discusses how DTNs can better handle high and variable delays and disruptions compared to TCP/IP networks by introducing a bundle layer above the transport layer. The security goals of DTNs include hop-by-hop integrity and authentication as well as end-to-end integrity, authentication, and confidentiality. Key management in DTNs requires an efficient and communication-friendly approach to support public key cryptography and the overall DTN security architecture.

A Trust-Based Predictive Model for Mobile Ad Hoc Networks
The Internet of things (IoT) is a heterogeneous network of different types of wireless networks such as wireless sensor networks (WSNs), ZigBee, Wi-Fi, mobile ad hoc networks (MANETs), and RFID. To make IoT a reality for smart environment, more attractive to end users, and economically successful, it must be compatible with WSNs and MANETs. In light of this, the present paper discusses a novel quantitative trust model for an IoT-MANET. The proposed trust model combines both direct and indirect trust opinion in order to calculate the final trust value for a node. Further, a routing protocol has been designed to ensure the secure and reliable end-to-end delivery of packets by only considering trustworthy nodes in the path. Simulation results show that our proposed trust model outperforms similar existing trust models.
Delay telerant network
Delay tolerant networks (DTNs) allow communication in networks with intermittent connectivity by using a store-carry-forward approach. DTNs employ a set of protocols that store messages during network disconnections and forward them when connectivity is available. They can provide communication even when end-to-end paths do not exist. Key properties of DTNs include high latency, low data rates, disconnection, long queuing delays, short contact ranges, and dynamic topologies. Potential applications of DTNs include telemedicine in remote areas, social networking, communication under censorship, file sharing, and sharing cellular minutes.
TRUST ORIENTED SECURITY FRAMEWORK FOR AD HOC NETWORK
An ad hoc network is a group of wireless mobile hosts that are connected momentarily through
wireless connections in the dearth of any centralized control or some supporting services. The
mobile ad hoc network is at risk by its environment because of the vulnerabilities at channel and
node level. The conventional security mechanisms deals with only protecting resources from unauthorized access, but are not capable to safeguard the network from who offer resources. Adding trust to the on hand security infrastructures would improvise the security of these environments. A trust oriented security framework for adhoc network using ontological engineering approach is proposed by modeling ad hoc network, the OLSR (Optimized Link State Routing) protocol and trust model as OWL (Ontology Web language) ontologies, which are integrated using Jena. In this model, a trustor can calculate its trust about trustee and use the calculated trust values to make decisions depending on the context of the application or interaction about granting or rejecting it. A number of experiments with a potential implementation of suggested framework are performed to validate the characteristics of a trust oriented model suggested by the literature by this framework
Peer-to-Peer Communication Service and Messaging System
The peer-to-peer communication services[1] has entered into the public limelight over the last few
years. Several researches are underway on peer-to-peer communication technologies, but no definitive conclusion
is currently available. Comparing to traditional server client technology on the Internet, the peer-to-peer
technology has capabilities to realize highly scalable, extensible and efficient distributed applications. Our work
presents an anonymous peer-to-peer (P2P) messaging system. A P2P network consists of a large number of peers
interconnected together to share all kinds of digital content. A key weakness of most existing P2P systems is the
lack of anonymity. Without anonymity, it is possible for third parties to identify the participants involved. First,
anonymous P2P system should make it impossible for third parties to identify the participants involved. Second,
anonymous P2P system should guarantee that only the content receiver knows the content. Third, anonymous P2P
system should allow the content publisher to plausibly deny that the content originated from him or her.

An Enhanced Approach to Avoid Black hole Attack in Mobile Ad hoc Networks usi...
A mobile ad-hoc network (MANET) is very receptive to security attacks due to its open medium, dynamically changing network topology, lack of centralized monitoring. These vulnerabilities are nature of MANET structure that cannot be removed. As a consequence, attacks with malicious intent have been and will be devised to exploit these vulnerabilities and to cripple MANET operations. One of the well known attack on the MANET is the Black Hole attack which is most common in the ondemand routing protocols such as AODV. A black hole attack refers to an attack by a malicious node, which forcibly gains the route from a source to a destination by the falsification of sequence number and hop count of the routing message. This paper represents an enhanced AOMDV routing protocol for avoiding black hole attack in MANET. This routing protocol uses Ad hoc On-demand Multipath Distance Vector (AOMDV) to form link disjoint multi-path during path discovery to provide better path selection in order to avoid malicious nodes in the path using legitimacy table maintained by each node in the network. Nonmalicious nodes steadily isolate the black hole nodes based on the values collected in their legitimacy table and avoid them while making path between source and destination. The effectiveness of our approach is illustrated by simulations conducted using network simulator ns-2.34.

This document discusses the detection of black hole attacks in mobile ad hoc networks (MANETs) that use the Ad Hoc On-Demand Distance Vector (AODV) routing protocol. It proposes using authentication techniques including authenticated nodes, authentication on paths, authentication key packets, and a data routing information table on each node to detect black hole nodes. An example network is presented to demonstrate how the proposed techniques would detect a black hole node by analyzing authentication packet responses. The goal is to securely route data packets by detecting malicious nodes using these authentication methods.
Presentation.pptx
Mobile ad-hoc networks (MANETs) are wireless networks formed by mobile nodes without any preexisting infrastructure. Nodes are mobile and connected dynamically in an arbitrary manner. Routing protocols in MANETs can be proactive, reactive, or hybrid. Proactive protocols maintain routing tables through periodic exchanges while reactive protocols find routes on demand. MANETs are vulnerable to both passive and active attacks due to the lack of centralized coordination. Security goals for MANETs include confidentiality, integrity, availability, and authentication. Potential applications include military operations, sensor networks, emergency response, campus networks, and conferences.
Abdullah Mukhtar ppt
1- Mobile ad hoc networks are formed dynamically by an
autonomous system of mobile nodes that are connected
via wireless links.
2- Multihop communication- node communicate with the
help of two or more node from source to destination.
3- No existing fixed infrastructure or centralized administration –No base station.
4- Mobile nodes are free to move randomly-Network topology changes frequently
5- May Operate as standalone fashion or also can be connected to the larger internet.
6- Each node work as router
Primary Goals of Security in MANET
To assure a reliable data transfer over the communication networks and to protect the system resources a number of security services are classified in five categories:-
1-Authentication:- The process of identifying an individual , usually based on a username and password.
2- Confidentially:- Confidentiality aims at protecting the data from disclosure to unauthorized person.
Network attacks against confidentiality
* Packet capturing
Password attack
Port scanning
Dumpster Diving
Wiretapping
Phishing and Pharming
2-Non repudiation:- Integrity guarantees that a message being transferred is never corrupted.
3- Integrity:- Integrity guarantees that a message being transferred is never corrupted.
network attack against integrity
Salami attack
trust relationship attacks
Man in the middle attack
Session hijacking attacks
4- Availability:- Its ensure that data ,network resources or network services are available to legitimate user when required.
network attack against availability
Denial of services attacks
Distributed denial of services attack
SYN flood attacks and ICMP flood attacks
Electrical power attacks
Server Room environment attacks
Key management
The security in networking is in many cases dependent on proper key management.
Key management consists of various services, of which each is vital for the security
of the networking systems
* Trust model:-Its must determine how much different element in the network can trust each other.
* Cryptosystem:- Public and symmetric key mechanism can be applied .
* Key creation:- It must determine which parties are allowed to generate key to themselves.
* Key storage :- In adhoc network any network element may have to store its own key and possibly key of other element as well.
* Key distribution:- The key management service must ensure that the generated keys are securely distributed to their owners.
Survey paper on Detecting Blackhole Attack by different Approaches and its Co...
This document summarizes research on detecting blackhole attacks in mobile ad hoc networks (MANETs). It first defines MANETs and describes blackhole attacks, where malicious nodes drop packets to disrupt routing. The document then reviews several approaches for detecting single or cooperative blackhole attacks and compares their assumptions and effectiveness. It finds that while various methods have been proposed, consistently detecting multiple cooperative blackhole nodes remains a challenge, as detection requires cooperation between non-malicious nodes. Future work could involve further simulation-based comparison of detection method performances.
Trust Providence in Delay Tolerant Networks
The network consists of several nodes, some nodes represents malicious and selfish behavior. This gives the heavy threat for the routing in Delay Tolerant networks(DTNs). The DTNs have unique characteristic so designing a misbehavior detection scheme is very difficult. The probabilistic misbehavior detection scheme that is iTrust, is established for secure routing in DTN. The iTrust introduces a Trusted Authority (TA) for detecting the node’s behavior. By collecting the routing evidences from the nodes the TA checks the node about its behavior then performs the appropriate actions for the behavior of nodes. TA gives the security of DTN routing at lower cost. The detection probability is correlated with a node’s reputation, this gives the dynamic detection probability based on the trust of users. The simulation results show that the proposed scheme is efficient for establishing trust with the DTNs.

Behavioral Model to Detect Anomalous Attacks in Packet Transmission
This document summarizes a proposed behavioral model to detect anomalous attacks in packet transmission in wireless networks. The model aims to identify packet droppers and modifiers by having nodes monitor their neighbors' forwarding behaviors over time. A tree-based routing structure is used, where each packet is marked as it travels toward the sink node. The marks provide information to help the sink node determine which nodes are misbehaving. The proposed scheme aims to gradually identify bad nodes through statistical analysis of their behaviors across different network topologies over time, with low false positives. It aims to catch both packet droppers and modifiers within a single detection module.
Tracking message spread in mobile delay tolerant networks
The document proposes tracking the spread of messages in delay tolerant mobile networks using a Kalman filter. It summarizes the existing direct delivery system and its drawbacks of long delays and inability to track spread. The proposed system applies a Kalman filter to track message spread under different forwarding schemes in order to control dissemination. It demonstrates that tracking performance is comparable between homogeneous and heterogeneous mobility models.

This document discusses the detection of black hole attacks in mobile ad hoc networks (MANETs) that use the Ad Hoc On-Demand Distance Vector (AODV) routing protocol. It proposes using authentication techniques including authenticated nodes, authentication on paths, authentication key packets, and a data routing information table on each node to detect black hole nodes. An example network is presented to demonstrate how the proposed techniques would detect a black hole node by analyzing authentication packet responses. The goal is to securely route data packets by detecting malicious nodes using these authentication methods.
Presentation.pptx
Mobile ad-hoc networks (MANETs) are wireless networks formed by mobile nodes without any preexisting infrastructure. Nodes are mobile and connected dynamically in an arbitrary manner. Routing protocols in MANETs can be proactive, reactive, or hybrid. Proactive protocols maintain routing tables through periodic exchanges while reactive protocols find routes on demand. MANETs are vulnerable to both passive and active attacks due to the lack of centralized coordination. Security goals for MANETs include confidentiality, integrity, availability, and authentication. Potential applications include military operations, sensor networks, emergency response, campus networks, and conferences.
Abdullah Mukhtar ppt
1- Mobile ad hoc networks are formed dynamically by an
autonomous system of mobile nodes that are connected
via wireless links.
2- Multihop communication- node communicate with the
help of two or more node from source to destination.
3- No existing fixed infrastructure or centralized administration –No base station.
4- Mobile nodes are free to move randomly-Network topology changes frequently
5- May Operate as standalone fashion or also can be connected to the larger internet.
6- Each node work as router
Primary Goals of Security in MANET
To assure a reliable data transfer over the communication networks and to protect the system resources a number of security services are classified in five categories:-
1-Authentication:- The process of identifying an individual , usually based on a username and password.
2- Confidentially:- Confidentiality aims at protecting the data from disclosure to unauthorized person.
Network attacks against confidentiality
* Packet capturing
Password attack
Port scanning
Dumpster Diving
Wiretapping
Phishing and Pharming
2-Non repudiation:- Integrity guarantees that a message being transferred is never corrupted.
3- Integrity:- Integrity guarantees that a message being transferred is never corrupted.
network attack against integrity
Salami attack
trust relationship attacks
Man in the middle attack
Session hijacking attacks
4- Availability:- Its ensure that data ,network resources or network services are available to legitimate user when required.
network attack against availability
Denial of services attacks
Distributed denial of services attack
SYN flood attacks and ICMP flood attacks
Electrical power attacks
Server Room environment attacks
Key management
The security in networking is in many cases dependent on proper key management.
Key management consists of various services, of which each is vital for the security
of the networking systems
* Trust model:-Its must determine how much different element in the network can trust each other.
* Cryptosystem:- Public and symmetric key mechanism can be applied .
* Key creation:- It must determine which parties are allowed to generate key to themselves.
* Key storage :- In adhoc network any network element may have to store its own key and possibly key of other element as well.
* Key distribution:- The key management service must ensure that the generated keys are securely distributed to their owners.
Survey paper on Detecting Blackhole Attack by different Approaches and its Co...
This document summarizes research on detecting blackhole attacks in mobile ad hoc networks (MANETs). It first defines MANETs and describes blackhole attacks, where malicious nodes drop packets to disrupt routing. The document then reviews several approaches for detecting single or cooperative blackhole attacks and compares their assumptions and effectiveness. It finds that while various methods have been proposed, consistently detecting multiple cooperative blackhole nodes remains a challenge, as detection requires cooperation between non-malicious nodes. Future work could involve further simulation-based comparison of detection method performances.
Trust Providence in Delay Tolerant Networks
The network consists of several nodes, some nodes represents malicious and selfish behavior. This gives the heavy threat for the routing in Delay Tolerant networks(DTNs). The DTNs have unique characteristic so designing a misbehavior detection scheme is very difficult. The probabilistic misbehavior detection scheme that is iTrust, is established for secure routing in DTN. The iTrust introduces a Trusted Authority (TA) for detecting the node’s behavior. By collecting the routing evidences from the nodes the TA checks the node about its behavior then performs the appropriate actions for the behavior of nodes. TA gives the security of DTN routing at lower cost. The detection probability is correlated with a node’s reputation, this gives the dynamic detection probability based on the trust of users. The simulation results show that the proposed scheme is efficient for establishing trust with the DTNs.
Delay Tolerant Network - Presentation

Behavioral Model to Detect Anomalous Attacks in Packet Transmission
This document summarizes a proposed behavioral model to detect anomalous attacks in packet transmission in wireless networks. The model aims to identify packet droppers and modifiers by having nodes monitor their neighbors' forwarding behaviors over time. A tree-based routing structure is used, where each packet is marked as it travels toward the sink node. The marks provide information to help the sink node determine which nodes are misbehaving. The proposed scheme aims to gradually identify bad nodes through statistical analysis of their behaviors across different network topologies over time, with low false positives. It aims to catch both packet droppers and modifiers within a single detection module.

Distributed routing
This document discusses using SDN and OpenFlow to implement distributed routing in CloudStack. It describes how traditional VPC deployment has issues like traffic trombone effects and single points of failure. The CloudStack solution uses Open vSwitch bridges on each host configured by a CloudStack controller to act as logical routers, performing distributed routing for east-west traffic within a VPC while continuing to use VPC virtual routers for north-south traffic. It explains how the CloudStack controller populates the OpenFlow tables on each host bridge to implement the distributed routing and ACL policies.

A017320105
This document discusses routing and security issues for trust-based frameworks in mobile ad hoc networks (MANETs). It begins by defining MANETs and explaining that routing protocols play an important role in discovering optimal paths between nodes. However, the dynamic and unpredictable nature of MANETs makes routing difficult. The document then examines security issues for MANETs including attacks from malicious nodes. It argues that establishing trust between nodes is important for routing and security. However, existing trust-based routing proposals have issues that are not clearly addressed, such as how to calculate and establish trust between nodes. The document concludes by stating that addressing these open issues could help develop more efficient and robust trust-based routing protocols for MANETs.

Open Systems Interconnection
The OSI model is a conceptual framework that characterizes computing functions into a set of rules to support interoperability between networking systems. It divides network communication processes into seven smaller layers - physical, data link, network, transport, session, presentation, and application layer. Each layer has a specific role like the physical layer deals with transmission of raw bits, the network layer handles routing between devices, and the application layer supports programs that use the network. The model allows networks with different hardware and software to communicate in a standard way.
Analysis Of Wireless Sensor Network Routing Protocols
This document proposes using Border Gateway Protocol (BGP) and inter-domain packet filters (IDPFs) to limit IP spoofing on the internet. IDPFs would be constructed using information from BGP route updates and deployed on border routers. IDPFs aim to minimize IP spoofing without requiring global routing information. The framework is designed so that it does not incorrectly discard packets with valid source addresses. With even partial deployment, IDPFs could reduce the level of IP spoofing on the internet.

This document summarizes a research paper that proposes using a hotspot algorithm to improve node stability in mobile ad hoc networks (MANETs). The paper first provides background on MANETs and challenges with routing in dynamic network topologies. It then discusses the importance of node stability and proposes using a hotspot algorithm to identify stable nodes. The algorithm calculates stability factors for nodes based on their mobility and neighbors' mobility. Routing is done through stable nodes to improve efficiency. The paper models this approach in a network simulator and analyzes results on parameters like packet loss and throughput. Future work involves further optimizing the network using this routing method.

A Fast-Acquisition All-Digital Delay-Locked Loop Using a Starting-Bit Prediction Algorithm for the Successive-Approximation Register
This brief presents a fast-acquisition 11-bit all-digital delay-locked loop (ADDLL) using a novel starting-bit prediction algorithm for the successive-approximation register (SBP-SAR). It can effectively eliminate the harmonic lock and the false lock. The achievable acquisition time is within 17.5-23.5 or 17.5-32.5 clock cycles when the ADDLL works at the low or high clock rate, respectively. The digital-controlled delay line and the SBP-SAR of the ADDLL chip are synthesized using Taiwan Semiconductor Manufacturing Company's (TSMC's) 0.18-μm CMOS cell library. The proposed ADDLL can operate at a clock frequency from 60 MHz to 1.1 GHz.

This document describes a proposed stochastic implementation of the Sauvola local image thresholding algorithm to reduce area, power consumption, and faults compared to a conventional implementation. The stochastic implementation converts pixel values and intermediate results to stochastic bit streams, uses stochastic multiplying counters (SMCs) to calculate averages and standard deviations in parallel, and a stochastic comparator to determine binary output values. Experimental results using Xilinx 14.2 show the stochastic implementation requires less time, area and power while being more fault tolerant.

A Dynamically Reconfigurable Multi-ASIP Architecture for Multistandard and Multimode Turbo Decoding
The multiplication of wireless communication standards is introducing the need of flexible and reconfigurable multistandard baseband receivers. In this context, multiprocessor turbo decoders have been recently developed in order to support the increasing flexibility and throughput requirements of emerging applications. However, these solutions do not sufficiently address reconfiguration performance issues, which can be a limiting factor in the future. This brief presents the design of a reconfigurable multiprocessor architecture for turbo decoding achieving very fast reconfiguration without compromising the decoding performances.

Interleaved digital power factor correction based on the sliding mode approach
Interleaved Digital Power Factor Correction Based on the Sliding-Mode Approach
This study describes a digitally controlled power factor correction (PFC) system based on two interleaved boost converters operating with pulsewidth modulation (PWM). Both converters are independently controlled by an inner control loop based on a discrete-time sliding-mode (SM) approach that imposes loss-free resistor (LFR) behavior on each cell. The switching surface implements an average current-mode controller so that the power factor (PF) is high. The SM-based digital controller is designed to operate at a constant switching frequency so that the interleaving technique, which is recommended for ac-dc power conversion systems higher than 1 kW, can be readily applied. An outer loop regulates the output voltage by means of a discrete-time proportional-integral (PI) compensator directly obtained from a discrete-time small-signal model of the ideal sliding dynamics. The control law proposed has been validated using numerical simulations and experimental results in a 2-kW prototype.

Bumpless control for reduced thd in power factor correction circuits
Bumpless Control for Reduced THD in Power Factor Correction Circuits
It is well known that power factor correction (PFC) circuits suffer from two fundamentally different operating modes over a given AC input cycle. These two modes, continuous conduction mode (CCM) and discontinuous conduction mode (DCM), have very different frequency-response characteristics that can make control design for PFC circuits challenging. The problem is exacerbated by attempts to improve efficiency by dynamically adjusting the PWM switching frequency based on the load. Adjusting the PWM frequency based on the load limits controller bandwidth and restricts dynamic performance. Prior work has made use of multiple controllers, however, they have not addressed the discontinuity (bump) that exists when switching between controllers. In this paper, bumpless controllers will be synthesized for a 750 watt, semi-bridgeless PFC for the CCM-DCM operating modes.

A bidirectional single-stage three-phase Rectifier with high-frequency Isolation and power factor Correction
This paper proposes a single-stage three-phase rectifier with high-frequency isolation, power factor correction, and bidirectional power flow. The presented topology is adequate for dc grids (or smart-grids), telecommunications (telecom) power supplies, and more recent applications such as electric vehicles. The converter is based on the three-phase version of the dual active bridge (DAB) associated with the three-state-switching cell (3SSC), whose power flow between the primary and secondary sides is controlled by the phase-shift angle. A theoretical analysis is presented and validated through simulation and experimental.

A bidirectional three level llc resonant converter with pwam control
A Bidirectional Three-Level LLC Resonant Converter With PWAM Control
This paper proposes a bidirectional three-level LLC resonant converter with a new pulse width and amplitude modulation control method. With different control signals, it has three different operation modes with different voltage gains. Therefore, it can achieve wide voltage gain range by switching among these three modes, which is attractive for energy storage system applications needing wide voltage variation. The proposed topology operates with constant switching frequency, which is easy to implement with digital control, and it can achieve soft switching for all the switches and diodes in the circuit as a conventional LLC resonant converter. The performance of the proposed converter is validated by the experimental results from a 1-kW prototype with 20 A maximum output current.

Efficient single phase transformerless inverter for grid tied pvg system with...
This document describes a proposed transformer-less inverter topology for grid-tied photovoltaic systems. The existing dual-parallel buck converter topology has issues where the grid can short circuit if there is no dead time between switches. The proposed topology addresses this by using six MOSFET switches and six diodes in a configuration that allows reactive power injection while overcoming reliability issues. It has advantages like utilizing only MOSFET switches, low leakage current, and not requiring PWM dead times. The proposed single-phase inverter is intended for grid-tied PV applications.

Highly Reliable Transformerless Photovoltaic Inverters With Leakage Current and Pulsating Power Elimination
This paper presents a transformerless inverter topology, which is capable of simultaneously solving leakage current and pulsating power issues in grid-connected photovoltaic (PV) systems. Without adding any additional components to the system, the leakage current caused by the PV-to-ground parasitic capacitance can be bypassed by introducing a common-mode (CM) conducting path to the inverter. The resulting ground leakage current is therefore well controlled to be below the regulation limit. Furthermore, the proposed inverter can also eliminate the well-known double-line-frequency pulsating power that is inherent in single-phase PV systems. By properly injecting CM voltages to the output filter capacitors, the pulsating power can be decoupled from the dc-link. Therefore, it is possible to use long-lifetime film capacitors instead of electrolytic capacitors to improve the reliability of the PV system. The mechanism of leakage current suppression and the closed-loop control of pulsating power decoupling are discussed in this paper in detail. A 500-W prototype was also built and tested in the laboratory, and both simulation and experimental results are finally presented to show the excellent performance of the proposed PV inverter.

Grid current-feedback active damping for lcl resonance in grid-connected volt...
Grid-Current-Feedback Active Damping for LCL Resonance in Grid-Connected Voltage-Source Converters
This paper investigates active damping of LCL-filter resonance in a grid-connected voltage-source converter with only grid-current feedback control. Basic analysis in the s-domain shows that the proposed damping technique with a negative high-pass filter along its damping path is equivalent to adding a virtual impedance across the grid-side inductance. This added impedance is more precisely represented by a series RL branch in parallel with a negative inductance. The negative inductance helps to mitigate phase lag caused by time delays found in a digitally controlled system. The mitigation of phase-lag, in turn, helps to shrink the region of nonminimum-phase behavior caused by negative virtual resistance inserted unintentionally by most digitally implemented active damping techniques. The presented high-pass-filtered active damping technique with a single grid-current feedback loop is thus a more effective technique, whose systematic design in the z-domain has been developed in this paper. For verification, experimental testing has been performed with results obtained matching the theoretical expectations closely.

Delay-Dependent Stability of Single-Loop Controlled Grid-Connected Inverters with LCL Filters
LCL filters have been widely used for grid-connected inverters. However, the problem that how time delay affects the stability of digitally controlled grid-connected inverters with LCL filters has not been fully studied. In this paper, a systematic study is carried out on the relationship between the time delay and stability of single-loop controlled grid-connected inverters that employ inverter current feedback (ICF) or grid current feedback (GCF). The ranges of time delay for system stability are analyzed and deduced in the continuous s-domain and discrete z-domain. It is shown that in the optimal range, the existence of time delay weakens the stability of the ICF loop, whereas a proper time delay is required for the GCF loop. The present work explains, for the first time, why different conclusions on the stability of ICF loop and GCF loop have been drawn in previous studies. To improve system stability, a linear predictor-based time delay reduction method is proposed for ICF, while a time delay addition method is used for GCF. A controller design method is then presented that guarantees adequate stability margins. The delay-dependent stability study is verified by simulation and experiment.

Pass byo bring your own picture for securing graphical passwords
This document describes PassBYOP, a new graphical password scheme that uses live video of a physical token (such as a photo on a mobile phone) rather than static digital images. Three feasibility studies examine its reliability, usability, and security against observation attacks. Results found passwords based on image features to be viable, with task times and error rates comparable to prior schemes. Using a user-owned physical token increased security against observation without additional user burden, showing promise for more secure graphical passwords.

Analyzing ad library updates in android apps
The document discusses analyzing ad library updates in Android apps. It finds that almost half of Android apps underwent ad library updates over a 12 month period, where an ad library was added, removed, or updated. For nearly 14% of app updates with an ad library update, no changes were made to the app's core functionality, suggesting maintaining ad libraries requires substantial effort. The proposed system compares how apps are updated over time to determine if an update includes ad library changes, core changes, or both.

Webinar: Designing a schema for a Data Warehouse
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.

- 7. Abstract Delay tolerant networks (DTNs) are characterized by high end-to-end latency, frequent disconnection, and opportunistic communication over unreliable wireless links. In this paper, we design and validate a dynamic trust management protocol for secure routing optimization in DTN environments in the presence of well-behaved, selfish and malicious nodes. We develop a novel model-based methodology for the analysis of our trust protocol and validate it via extensive simulation. Moreover, we address dynamic trust management, i.e., determining and applying the best operational settings at runtime in response to dynamically changing network conditions to minimize trust bias and to maximize the routing application performance. We perform a comparative analysis of our proposed routing protocol against Bayesian trust-based and non-trust based (PROPHET and epidemic) routing protocols. The results demonstrate that our protocol is able to deal with selfish behaviors and is resilient against trust-related attacks. Furthermore, our trust-based routing protocol can effectively trade off message overhead and message delay for a significant gain in delivery ratio. Our trust-based routing protocol operating under identified best settings outperforms Bayesian trust-based routing and PROPHET, and approaches the ideal performance of epidemic routing in delivery ratio and message delay without incurring high message or protocol maintenance overhead
- 8. Introduction Many studies focus on information theoretical and physical layer aspects, such as link capacity, coding, and relay positioning in simple scenarios often with only three nodes The study of cooperative diversity in large networks and the design of link-layer protocols enabling the use of relays has found less attention. We believe that cooperative diversity will not be implemented in practice until protocols supporting the physical layer to exploit the benefits of diversity are designed and properly specified. To this end, we focus on the design of Medium Access Control (MAC) protocols for cooperative relay systems and specify design blocks of a MAC protocol that can be readily incorporated into existing wireless systems.
- 9. EXISTING SYSTEM A delay tolerant network (DTN) comprises mobile nodes (e.g., humans in a social DTN) experiencing sparse connection, opportunistic communication, and frequently changing network topology. Because of lack of end-to-end connectivity, routing in DTN adopts a storecarry- and-forward scheme by which messages are forwarded through a number of intermediate nodes leveraging opportunistic encountering, hence resulting in high end-to-end latency.
- 10. PROPOSED SYSTEM • Social trust deriving from social networks and traditional quality of service (QoS) trust deriving from communication networks into a composite trust metric to assess the trust of a node in a DTN. To cope with both malicious and socially selfish nodes, we consider “healthiness” and “unselfishness” as two social trust metrics. • The issue of application performance maximization (trust-based DTN routing in this paper) through dynamic trust management by adjusting trust aggregation/formation protocol settings dynamically in response to changing conditions to maximize DTN routing performance. Essentially we address the importance of integration of trust and security metrics into routing and replication decisions in DTNs.
- 11. Advantages • Allows the best trust setting for trust aggregation to be identified so that subjective • trust is closest to objective trust for each individual trust property for minimizing trust bias. • We performed a comparative analysis of trust-based secure routing running on top of our trust management protocol with Bayesian trustbased routing and non-trust-based routing protocols (PROPHET and epidemic) in DTNs. • DTN routing performance and developing trust and security management protocols for delay-tolerant, self-contained message forwarding applications based on the information-centric networks (ICN) architecture.
